Comparison of Single- and Bi-Tuned Mass Dampers under Equal Total Auxiliary Mass and Different Dynamic Loads in a Wind Turbine Tower–Nacelle System

Öz

This study compares a single tuned mass damper and a bi-tuned mass damper in a single-degree-of-freedom wind turbine tower–nacelle model. Four configurations are evaluated under the same total auxiliary mass: the classical Den Hartog design, a single damper retuned with the common objective, a bi-tuned damper with equal branch masses, and a bi-tuned damper with a free mass split. The objective combines normalized displacement and acceleration responses over a frequency band around the main natural frequency, and the designs are optimized for total auxiliary mass ratios of 0.02, 0.05, and 0.20. A coarse sweep is followed by a toolbox-free particle swarm optimization; independent differential evolution, extended-bound searches, equal-split coverage, and internal consistency checks are used for verification. The equal-branch bi-tuned damper gave a lower band objective than the retuned single damper at all three mass ratios. The free-split search did not improve on the equal split at the two lower mass ratios and provided only a small additional gain at 0.20. The retuned single damper performed best under single-frequency harmonic loading, whereas both bi-tuned configurations yielded marginally lower objective values under the chirp load. For ten zero-mean Kaimal realizations normalized to 100 N root mean square, paired analysis at a mass ratio of 0.20 identified small but statistically significant differences; the equal-branch bi-tuned damper had the lowest mean objective. Frequency-response and ±10% natural-frequency-deviation analyses showed that two tuning branches redistribute the response across the band, but do not provide unconditional detuning robustness. The practical choice therefore depends not only on the objective value but also on stroke demand, transmitted force, component count, and maintenance requirements.
